Abstract

Abstract: Background: COVID-19 (C-19) infection can acutely cause organ dysfunctions, especially cardiorespiratory, even with a long recovery period, inducing a significant functional deficit. Aim of the study was to evaluate the impact of a holistic hospital intensive rehabilitation program, based on CR, on C-19 patients (P), after acute care, to improve their fitness, in order to return to their life in the best conditions. Methods: In the period april-august 2020, 30 P (mean age 73 years, 60% male) were admitted to the rehabilitation centre at a mean distance of 31±11 days from the onset of C-19; 34% of them had undergone prolonged invasive ventilation, 34% non invasive ventilation and 32% required high flow oxygen. Comorbidities were: hypertension (77%), diabetes (13%) and chronic coronary syndrome (10%); 18 P were unable to stand, and 12 showed impaired trunk control. No P had impaired LVEF or significant valvular disease. Initially, the program focused on training for trunk and sitting control; then on exercises for straightening the upper and lower limbs. From the second week, started a CR training on the cycle ergometer 10–20 minutes a day for 6 days a week, similar protocol to that used in P with heart failure. The aerobic training was of moderate intensity, not exceeding 40–60% of the maximum heart rate, Borg scale 10–12, starting with zero load, gradually increasing by 10–15 watts and up to a minimum target of 25–30 watts. The impact of the protocol on motor functions [MRC Muscle Strenght Scale, Short Physical Performance Battery (SPPB)] on functional capacity [6 Minutes Walking Test (6MWT)] on anxiety (A) and depression (D) [Hamilton Anxiety Rating scale (HAMA) and Hamilton Depression Rating scale (HAMD)] and on basic activities of daily life [Barthel Index (BI)] were evaluated. The assessment was done on the admission (T0), at the discharge (T1, on average after 31 days) and after a follow-up of 55 days (T3). Results: The results are shown in the table below. Only 4 P were able to perform the 6MWT at T0. The motor function improves rapidly and then reaches a plateau and its trend is reflected in the BI. Functional capacity, on the other hand, improves significantly even at a distance. A and D decreased rapidly but increased over time. Conclusions: A rehabilitation protocol, centered on CR, induces a rapid increase in motor capacity, even in severely compromised subjects such as C-19. The improvement in fitness over time, as demonstrated by the 6MWT, probably is due to the severe muscle deconditioning, for the long stay in acute care. The long-term worsening of A and D may depend on various causes: no longer living in a "protected and safe" place, the fear of relapse, returning home and discovering new deaths and mournings. A program, CR-like, can counteract many of the negative consequences of C-19; however these P deserve an outpatient rehabilitation to maintain and consolidate the positive results over time.
